Specification of Letters Patent,

Patented Mar, its. 2 Qt Application filed April 4;, 1912. Serial 5J0,688.472

To all IP/ZHHZ if may concern Be it known that I, Bronson) T. IllYLL'ETIand Joux ll, illcKrrvev, citizens of the l'nitcd States. residin; atLatrobe. in the county of ll'cstmoreland, State of Pennsylvania. haveinvented a new and useful Valve, of which the following a specification.i

v This invention relates to an improvement in valves.

The primary object of the present invention is to provide an attachmentfor faucets, which will permit the valvestem to be removed and repaired,without cutting oil the supply of water.

A further object of the present invention is to provide means foropening the valve permitting-'the escape of water and air when thesupply ofwater has been cut'ofi' at a point remote from the valve.

A still further object of the present invention is to provide meansacted upon by the water previous to its exit through the faucet, forcausing the delivery of the water in a solid stream, thereby preventingsplashing.

A still further objectis to provide a valve structure in which thevarious washers, etc, may be removed and replaced without pen mittingthe escape of water through the faucet.

With the foregoing and other objects inview which will appear as thedescription proceeds, the invention resides in the combi-' nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed. it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

Figure l is a sectional view. Fig. 9 is a detail view of the valvemember. Fig. 3 a detail view of the lower end of the valve In thedrawings, 10 designates a faucet. The faucet. receives the stem 11 whichat a point adjacent its base is formed with the annular groove 12connnunicatinp, with the vertically disposed bore 14, a passage 15 whichenters the stem through the groove 12 communicating with the verticallydisposed cation with the outlet 16 of the same. The

lower terminal of the stem is provided with a "washer 1?, saidwashcrseating upon the valve seat 1%. Disposed for movement within thechamber- 19 is a cylindrical-valve member '20 which is formed with aplurality of slots 21, and the vertically disposed conical extension 22the apex of which projects within the borc'll and closes the same, thewater outlet 16 thus being cut otl whenthe washer is seated uponthese-at 18, the pressure of the water holding the floating valve memberin the position shown in Fig. 1. ll'hen it is desired to remove thevalve stem to place a new washer on the same, orrenew the stem orrepairthe same,

the stem is IQXTIOYGCh-tllB water pressure forcing the valve member 20which is provided with the bevel portion 24: in contact with the bevelportion 26 of the casing, cutting 05 the supply of water from the outlet16, the-water pressure retaining the member 20 in. this position. Afterthe stem or washer has been repaired the stem is again placed within thecasing: and as it is screwed down the member 20 is again forced intoposition as shown in Fig 1. the pressure of the water at the same timemain taining the conical extension 29 within the bore 14. It will henoted by this construetion that the valve stem may be readily rcmovedand replaced without cutting oti' the supply of water.

The valve is opened by rotating stem 11 so as to causethe washer lZ-tolift, off of its seat 18, the water thus being permitted to flow overthe valve member 20 and around the conical extension 32 after which itpasses out between washer 17 and seat- 18. The water which passesthrough the faucet when the valve is open is directed against the concave portion 25 of the member 20, and against the washer 17. thusbreaking the force of the water, deadening the same and allowing it totlow through the outlet 16 in a solid stream, preventing splashing.

lVhen it is desired to cut oft the supply of the water pressure isturned on again the valve member-2O will remain seated on cap 27 anowing air to escape from pipe through passage 15 to outlet 16 and whenwater pressure strikes member 20 it will rise oil? passage 15.

It will be noted that the device may be easily and economicallymanufactured, and that the various parts may be readily assembled.

Having thus described the invention, what is claimed as new is 1. Afaucet comprising a casing, a valve stem disposed within said casingsaid stem normally seated across the passage between the inlet andoutlet openings of the casing, said valve stembeing formed with avertically disposed bore and a transverse passage communicating withsaid here and With the outlet of the using, a pressure actuated valvemember-disposed within the casing, said valve member being provided witha conical extension adapted to close the bore in said valve stem, saidvalve member forming a closure for the passage between the inlet andoutlet of the casing when the valve stem is removed.

2. A. faucet comprising a casing, a valve stem normally seated acrossone end of the passage between the inlet and outlet of said said valvestem being formed adja'cent its base with a circumferential groove, saidvalve stem being provided with a centrally disposedbore and a passagecommunicating with the said bore and with said groove, and meansseparate from and located entirely outside of the valve stem, fornormally closing said bore, said bore being opened when the waterpressure ceases.

A faucet, comprising a casing, a valve stem disposed within said casing,said valve stem normally seated across the passage he and close I l l ll r l insatiatween'the inlet and outlet portions of said casing saidvalve stem being provided with a vertlcally disposed bore and atransverse passage which communicates with said bore and the outlet ofsaid casing, and a pressure actuating member separate from and locatedentirely outside of the valve stem and normally forming a closure forsaid bore.

4. A faucet comprising a casing, a valve stem disposed within the saidcasing, said valve stem normally seated across the passage between theinlet and outlet, of the casing a cylindrical member disposed formovement between said inlet and outlet said member adapted to form aclosure for the passage between the inlet and outlet when the valve stemis removed, said valve stem. being formed with a vertically dis posedbore, and a transverse passage which communicates with said bore and aconical extension formed integral with the valve member, said. conical'extensitm normally forming a closure for said bore.

it faucet. comprising a casing, a valve stem arranged within saidcasing, a washer upon the stem, said washer being normally seated acrossone end oi the passage between the inlet and outlet of the casing, andpressure actuated means for deflecting the water from the inlet to theperiphery of the washer. p

in testimony that we claim the foregoing as our own, we have heretoaiiixed our signatures in the presence of two witnesses.
